IMPROVEMENT lN WAGON-AXLE SLEEVES.

Specification forming part of Letters Patent No. 200,519, dated February19, 1878; application filed October 20, 1877. a

To an whom it may concern:

Be it known that I, JOHN DICKENS, of Kingston, in the county ofMiddlesex and State" of New Jersey, have invented certain new and usefulImprovements in Carriage and Wagon Axles; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification, in which- Figure 1 is a longitudinalvertical section of my invention. Fig. 2 is an elevation of the same.Figs. 3 and 4 are transverse vertical sections; and Fig. 5, a detailview, showing an elevation of the sleeve which surrounds the end of theaxle.

My invention has relation to that class of wagon or carriage axles inwhich the axlejournal is provided with an adjustable sleeve, which maybe turned on the journal when the under side becomes flattened and worn.

My invention consists in the novel construction, combination, andarrangement of parts and devices for securing the sleeve to the axle,and allowing it to be readily adjusted when required, all as hereinafterdescribed and claimed.

Referring to the accompanying drawing, A designates a carriage or wagonaxle, having rounded ends or journals B. Said axle is upset or enlargedat a, and threaded, as shown at a Said axle is also threaded at a whereit is provided with a screw-collar or washer, G, which fits tightlyagainst the shoulder or enlargement a.

D is a sleeve, which surrounds the journal B, having an external annularflange or shoulder, d, which rests against the screw-collar G.

E is another screw-collar, formed with an internal shoulder or annularflange, e, which meets the shoulder at on the sleeve D. The sleeve D,being slid on the journal B, is held fixedly in place by means of thecollar E, which screws on the upset part or enlargement a of the axle A,the shoulder e pressing the shoulder d against the collar 0.

When the sleeve D becomes worn or flattened by use the collar E isunscrewed sufficiently to relieve said sleeve. To loosen said sleeve onthe journal B, the collar 0 is now unscrewed slightly, causing thesleeve D to he slid out on the journal until it is loose and can beeasily revolved on the latter. The sleeve is now turned on the journalon its longitudinal axis sufficiently to bring its worn or flattenedpart on the side of the journal. The collar E is then screwed on, asbefore, holding the sleeve fixedly in place against the collar 0 untilit again becomes flattened and requires further turning.

The collar E, besides holding the sleeve in place on the journal andpreventing its turning when in use, serves to strengthen the axle at thepoint where breakage usually occurs yin, where the journal begins.

;' What I claim as my invention is- {The combination, with the axle A,having the separate threaded portions a a of different diameters, of theadjustable sleeve D, flanged at d, and the external and internalscrew-collars O E, the latter being flanged at 6, all substantially asand for the purpose described.

In testimony that I claim the foregoing I have hereunto set my handvthis 11th day of October, 1.877.
